为研究复合型煤泥旋流器的分级分选效果,介绍了复合型煤泥旋流器的结构,分析了复合型煤泥旋流器的工作原理,在对复合型煤泥旋流器流场数值模拟研究结论的基础上,对先分级后分选和先分选后分级2种复合型煤泥旋流器结构进行设计,并对分级分选效果进行了试验研究。结果表明:2种复合型煤泥旋流器都有明显的分级和分选效果,先分级后分选结构复合型煤泥旋流器分级分选效果优于先分选后分级结构复合型煤泥旋流器,旋流器最佳结构参数和操作参数有待后续试验进一步完善。

In order to study the classifying and separating effect of composite slime cyclone, the structure of composite slime cyclone was introduced, and the worki ng principle was analyzed, and on the basis of the conclusions of flow field numerical simulation of the classifying and separating effects of composite slime cyclone, th e structures of classification before separation and separation before classification composite slime cyclone were designed, the testing system was constructed, and th e test was proceeded. The results showed two types could achieve obvious classifying and separation effect, but the classifying and separating effects of the classificati on before separation were better than that of the separation before classification.However, the best structure parameters of the composite slime cyclone and operating parameters needed to be studied.
